v GATE.

SPECIFICATION forming part of Letters Patent No. 781,047, dated January 31, 1905.

i l Application led July 29, 1904:. Serial No. 218,650. l l

T0 @ZZ whom it' :may concern."

Be it known that I, ORLo J. OHAPIN, a citizen of the United States, residing at Spring field, in the Vcounty of Sangamon and State of Illinois, have invented certain new and useful Improvements in Gates, of which the followf ing is such a full, clear, and exact description as will enable others skilled in the art to which it appertains to make and use my said .invention.

My invention relates to gates of that class commonly' known as jump-gates.

The purposes of my invention are to. provide a portable and stable structure adapted to support the gate-frame and connected parts, to provide improved means for simultaneously operating all oi' the arms supporting the gateframe, and to provide simple and effective means for connecting with vthe supporting structure the 'arms on which the gate-frame is mounted. v i

With these ends in view my invention consists of the novel features of construction and combinations of parts shown in the annexed drawings, to which reference is hereby made and in which similar reference-letters designate like parts in the several views.

Referring to the drawings, Figure l is a side elevation of the complete vgate closed. In this viewthe positions of the gate-frame and connected parts when the gate is partially open are indicated by dotted lines. Fig. 2is an enlarged partial vertical section on the line 2 Z of Fig. 1. Fig. 3 is an isometric projection of the supporting structure detached, and

Fig. 4 is lan enlarged partial vertical trans verse section on the line 4L 4: of Fig. l and shows the means for connecting the arms with the box.

The gate -frame, which is preferably oi wood, though other suitable material may be used, is rectangular in form and consists of upright piecesA in pairs, secured to and connecting parallel horizontal rails 'AQ which lie between the uprights. The pair of uprights at one end and the middle pair of uprights project somewhat above the top rail, as shown in Fig. l.

The main structure supporting the gateframe and connected parts 'consists'of a box B, kopen at one end and partially open at the of the box.` so as to partially close one'enol thereof and leave an opening b2, through which the gate moves between the end pieces. The box B may be secured in'position by stakes B', driven into the ground on each side of the box, or by any suitable securing device. Vertical posts D and D at suitable distance apart are secured on the side pieces 5 of the box by bolts F3. A cross-piece D2 connects the upper ends of the posts D.

Horizontal rails D3 respectively connect the upper ends of the posts Dwith lthe posts D. Two pairs of levers E turn onbolts e, passing through the levers and through the posts D and D' and connect the levers with the posts. Two pairs of arms F have their upperl ends pivotally connected with the uprightsA by bolts a and have their lower ends pivotally connected with the side pieces of the box B. Plates'F have integral hubs f, pierced by holes f'. The holes through the lower ends of the arms F lit around the hubs f. Bolts F2 pass through the plates F and through the side pieces b. `VVashersf2 on the bolts F2 bear against the sides of the arms Fand prevent lateral movement of the arms.

Connecting-rods E have one end pivotally connected with the lower ends oi' the levers E, respectively, and the other endy pivotally connected with the arms F, respectively.

Weights E2 are supported on the levers E by rods e' or equivalent devices and serve to counterbalance the gate-frame and the arms on which it is mounted to such extent that a slight quick pull on either of the handles g2 will sulice to raise the gate-frame and carry it beyond the centers oi' the lower axes ofthe arms F, so that' the gate -i'rame will after passing the center gravitate to open or close the gate, as the case may be. There are two weights E2. A single weight E2 is connected to the upper ends of both levers E on each side of the gate.

A latch G, mounted between the uprights A at one end of the gate, has at its inner end an integral weight g, which gravitates to normally hold the other end of the latch in engagement with a suitable stop g on a stationary gate-post Gr. A cord g2 is connected with the latch Gr and passes through an eye ce on the gate-frame. Cords g3, connected with the cord.g2, are suitably supported on posts placed in the usual well-known position on either side ot the gate and have handles g2, which may be pulled to release the latch and raise the gate-frame, as hereinafter explained.

The box B, the posts D and D', the crosspiece D2, and the rails D3 constitute a Substantial and portable main structure or supporting-framefwhich may be secured on the ground in any desired position by stakes B', riven into the ground on each side of the In assembling the parts the post G is first firmly planted in a vertical position. The supporting structure is then placed in proper position relative to the post G and is leveled so that the posts D will extend vertically. The upper ends of the arms E are then connected with the upper ends of the uprights A, and the lower ends of the arms are connected with the sides of the box by the bolts F2, as already described. The levers E are then mounted on the posts D and D', the connecting-rods E are connected with the levers E and the arms F, and the weights E2 are connected with the upper ends ot' the levers E. The cords g2 and g3 are then connected with the latch, as described. The parts being assembled as described, the gate is in operative position, such that in order to either open or close the gate it is only necessary to pull quickly down and immediately release either of the handles g", thereby releasing the latch and raising the gate-frame over the center to the position indicated by dotted lines in Fig. 1, so that the frame will gravitate to open or close the gate, as the ease may be.

By employing the weighted levers E, arranged in pairs, one pair being connected with both of the arms E on one side of the gate-frame and the other pair being connected with both of the arms on the other side of the gate-frame, great uniformity of action is attained and the levers operate to move all oi?- the arms simultaneously, so as to cause the gate-frame to travel in a straight line and so as to prevent wabbling or rocking oi the gate-frame. This construction is of great practical advantage, because it greatly facilitates the operation ot' the gate and obviates the stopping of the gate on the center.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In agate, a main structure eonsistingof a box and vertical posts secured thereon, in combination with arms in pairs mounted to oscillate in said box, levers in pairs mounted on said main structure, weights connected with said levers, connecting-rods connecting` said levers with said arms, and a gate-trame pivotally connected with said arms, as set forth.

2. In a gate, the combination oi parallel vertical posts in pairs, levers in pairs mounted on said pairs ot' posts respectively, weights respectively connected with said pairs of levers, arms in pairs mounted to oscillate between the pairs or' posts, connecting-rods connecting both levers of one pair with both arms on one side of the gate-frame and connecting both levers of the other pail` with both arms on the other side or' the gate-frame, and a gate-frame mounted on said oscillating arms, as set forth.

In witness whereof I have hereunto subscribed my name, at Springfield, Illinois, this 30th day oi' June, 1904.
